Filed: 1978-12-28
Abstract: PURPOSE:To reduce the time for stabilization of copied images by detecting the potential differences of the bright and dark latent images through uniform light radiation of plural stepwise  quantities of light and determining a uniform light quantity change-bright-dark potential contrast  curve thereby controlling image stabilization. CONSTITUTION:For example, when the latent images of black and white paper corresponding to  the brightness and darkness of the original images provided at the leading end part of an original  platen 30 are formed on a photosensitive drum 1, the uniform light quantity from a lamp 13 for  uniform light is changed to plural steps by a bias power source 15 beforehand so as to be able to  cope with environment fluctuations, photoreceptor degradation, etc. and the poetential differences  of the bright and dark latent images formed on the drum 1 are detected with a probe 6. If these  are processed with a potentiometer 16, arithmetic part 20, etc., the relation of the potential contrast Vc and uniform light quantity change x corresponding to the potential differences of the  bright and dark latent images based on formula (Vc=ax<2>+bx+c) is determiened in a short  time. Hence, the light quantity change is controlled according to the potential differences of the  bright and dark contrasts of the images deteted by the probe 6, whereby the image contrast is stabilized. Because of this, the initial control is completed while the photosensitive drum makes 1  turn.

Abstract: PROBLEM TO BE SOLVED: To supply toner almost equal in amount to consumed toner by supplying the toner to a developing device only for a specific length of time each time the value of the total of the pixels of image data reaches a specific number. SOLUTION: When the input of the image data is applied to an interface, a printing operation starts. As information representing the number of the pixels of image data, the value of the total of the pixels is found by a pixel totalization/storage means 120. When the value of the total reaches the specific value, a motor control means 126 drives a toner supply motor only for the length of driving time corresponding to a grade selected by a selection means 124, and also the value of the total is zeroed again to make a flesh start of totalizing pixels. Then, only during a period of time that the toner supply motor is driven, toner is supplied to the first developing device and the second developing device from the toner supply device. Thus, each time the value of the total of the pixels of the image data reaches the specific value, the specific amount of toner is supplied.
